.To all whomitmay concern:

invented jcertain new and useful Improvements 1n Burnlshmg-Machmes, ofwhich the following isa specification.

The object'of my invention is to produce a 01193.1),15511111313, andhighlyv efiicient 'machineforlournishing or finishing leather articlesor the like, or any other kind of mav terial or art-iclefto be burnishedor finished.

The salient features of the invention consist in providing a; heatedslotted finger or:

burnishing tool Whichreciprocates or. oscillates in connection wlthpressure and oscillating feeding mechanism for automatically feeding thematerial toJbe burnished and thus imparting to the material areciprocating or oscillating fmovement while being burnished. I p

.The'various features and-advantages of the invention will readilybecome apparent from the following specification.

My machine consists of-Ia frame 1 providedwith an upwardand'forwardextending portion or arm 2; in the forward end of arm 2 Iplacevertical'bearings.3 and4,'see Fig. 6. The purpose of the bearingsvS and fl, is to hold the shaft 5 in a vertical position and'to allowsame to slide freely. Fasto Shaft at r;end,ipna a.

At theilower Patented A1 a said sorewactingasa stud oriaxis'for feed roller 8 which is also attached to saidarm'through medium of said screw; [The feed. roller ,8 has a knurledor'roughened surface as shown 111 Fig; 12. On the shaft?) and 7 betweenbearings 3 andf4, Ifastenc0l1an9.

vAroundshaft 5 and placedgbetween the bear- 1ng-3 and-collar 9,Icompres's the spring 10 as shown inFig. 5. The action of. spring 10against therigidbearing 3 and the collar '9 'onshaft, 5, is, to expandlaterally, thus cause ing a downward pressure :tothe shaft 5 and arm fiand consequently feed roller 8. l

I In the upward and forwardextending,

arn1.,2,'and' atv its middle, I construct bear'i ng 12. Through bearing12 I oscillate shaft 13 and at the upper end of shaft 13, I fastencollar" 14:. jAt the lower end Ofshaft 13, I securely fasten the housing15, Between the housing :15 andlower'end. of bearing12, I

place an asbestos washer 16.- -I hus"itcan be seen that the collar 14:acting'as athrust bearing against the upper face I of bean.

ing 12, will hold the housing 15 :in position. The housing 15 isconstructedso as to admit an electric unit .17 Atthe' forward end ofhousing 15, I securely fasten the burnishing 'toolo'r finger 18,projecting downward and.

away from the housing 15 ata suitable angle; see Fig. v6. Thus it willbeseenith'at when the electric current is applied; to' unit the lower endof tool '18, I place a slot'19.

,fIn jorder to oscillate toollS, I adoptj the 7' following means. In theupward and forward extending arm 2, I. place bea'r'ings120 and 21;see'Fig. 10. Through these bearing's the shaft 23.--is revolvedandllheldinposition by means of the collars-24-fand 25, which are-fastened toshaft 23. The forwardend of shaft '23, isturn'e'd smaller in diameterand offset, thus forming an eccentric 26. 'Journaled on thiseccehtric26, I

1 connect thelink27, as shown in Fig 10.

The other end of link 27 is journale'dlon the. stud 28, which is securedto housing 15,

. at bearing 29. Thus it can readily, be seen that when the shaft 23with its eccentric end is revolved, the housing will receive anoscillating motion, through themeans of.

the link 27 and its connections and also the finger 18, which beingconnected'to said.

housing, will reciprocate with it.

automatic feed ofmy machine is one of its important features forburnishing. My object is to feedthe lateral edges of the material to beburnished, through the "slot",-19,1 in the burnishingtool 18, and alsoto reversefthis feed, intermittently. To ob- .tain thisres ult'I adoptthe following means.

.in which I oscillate the shaft 32.

In the frame-1, 'I place bearings 30{ and 31, I V V I also place-thebearings 33 and 34 in the frame way or cam groove 44 to admit the roller45 ,as shown in Fig.8 The roller 45 is gconnectedto-the sliding arm46'by meansof a stud and must revolve fr eely on said stud. The sliding"arm 46, has a forked shaped end 47, which slides over and under the;shaft 38. The colla-r'63 on shaft 3'8'holds thesliclingarm -46 inposition against cam 41'. f-At'the otheren'd of the-arm 46, I connecttherocking arm 48, at the point 49.

' "The arm 48 is "fastenedto shaft 32. At-the forward end of shaft 32, Ialso fasten arm 50. At the upper end of arm '50, at the point 51, 1connect the feeding arm 52. The -=.'fee'ding arm 52', hasa fork shapedend 53, which slides over and under the roller 54.

"The roller 54, is fastened by means of a stud to; the arm55. Arm 55 isfastened to s-haft- 35 at, the forward end of said shaft.

The feedingarm' 52, is constructed'with a ffeedingplate 56; said platebeing held in pOSltlOIi by means of screws 57 and 58. The

topof the frame 1,-is cutaway at the point 59, to allow-the feedingplate 56, to extend *up through the frame land to come into contact withthe face of the feed roller 8;

*see Fig. 12. The top face of the feed plate 56, has a knurled orroughened surface, as

shown in Figs. 10 and '11.

*The feed roller 8, actuated bythe spring 10, has a downwardpressureupon the feed plate 56 and the downward travel of the "feedwheel 8, can be governed by the collar 9 on shaft 5, said collar beingadjustable, to and away from bearing 4, by means of a setscrew in collar9, the said collar 9 then acting as a stop against the lower bearing 4,thuslimiting thetravelof feed wheel 8.

On shaft 35, I'fasten arm 60 and on main shaft 38, I place the cam 61,as shown in Fig. 7. I The cam 61 is constructed with one lscribed, mustbe timed as follows. 41, with its double acting'noses 42 and 43, willgive a double oscillating action to shaft '32, during one revolution ofmain driving shaft 38, therefore shaft 32, with its double oscillatingaction. will give a double oscilnose 62; see Fig. 9. Connected to arm60, at-point 64, I have-the sliding arm 65, with a fork shaped end,passing over and under shaft 38- The roller 66 revolving against theface of the cam 61 and held in position holding the roller 66 againstthe working surfaccof 02111161. A collar 70, holds the arm in'posltionagainst the cam 61, as

shown in Fig. 7'. Power is applied to shaft 23' through pulley 75. Onshaft 23, I place spur gear 76 and on shaft 38', I place spur gear 77;the diameterof the gear 76 is one half the diameter of the gear 77 sothat the shaft 23 makes two complete revolutions "while the. shaft 38 ismaking one complete revolution.

i In order to get aperfect burnishing effect, the slot 19 in theburnishing tool 18 lies approximately in the plane in which the workengaging face of the feed plate 56 engages the work. The feedingnechanisnujust do The cam lating action to the feeding plate 56. The cam61, withits single acting nose, will give a single oscillating action toshaft 35. Therefore shaft 35, with its single oscillating 'action, will,through mechanism described,

drop the feed plate 56, below the surface of frame 1, thus causing anintermittent feed between the feed roller 8 and the feedplate 56.

The result obtained by this double action 0f the feed plate and thesingleaction of dropping the plate is as follows. The feed plate, withits forward and backward and forward action, and in contact with "feedroller 8, will feed the material forward and backward and forward again,the single acting cam then coming into operation and dropping the feedplate below the contact bearing between the material and the feed rolland the feed plate, will release the material. The feed plate-56,.whilein this position will then come back without feeding the material andagain be brought into contact with roller 8 by means of the singleacting cam. The double acting cam. then coming into operation repeatsthe function above set forth.

The material to be burnished or finished is placed upon the feed plate56 and adjacent thereto and between said feed plate and the feed roller8, the edge to'be burnished or finished extending into the slot 19 inthe burnising tool 18 and while the burnishing tool is oscillatingforward and backward the feed plate and roller are holding the materialin alinement and the feed plate is also oscil lating forward andbackward carrying the material with it; thus while the burnishing toolis working backward and forward the material is also beingworkedriorward and backward and thus a double action is exerted upon theedge of the material being burnished; this action preventing anydeteriorating or ill efi'ect upon the material; this action beingcontinuous and only. inter rupted when the feed plate 56 drops to beginrefeeding. By using my inventiondelicate' and easily marred surfaces canbe acted upon and properly burnished without de' stroying or injuringthem in any way. By

While I have described and shown eerf tain specific mechanism forcarrying out my invention, it will be readily seen that the same iscapable of considerable 1nodification and change without departing fromthe spirlt and prlnclple of my invention, and I wish to be understood asclaiming thatsuch modification and changes will still fall within thescope of my invention.
